WP Inline Comment Errors plug-in
Compatibility with other plug-ins
You may be using a 3rd party CAPTCHA plug-in with your comment form and you would like to show an error message if the user did not complete the captcha correctly.
In order to do this you may need to ‘hack’ the captcha plug-in code. There are two things you will need to determine. First you will need to review the plug-in code to find the validation function that determines if the captcha is correct. Second you will need to find the comment form filter hook that triggers the captcha validation function.
You will most likely need to create your own validation function and you can do this by copying and pasting the relevant code from the captcha plug-in validation function into your own function. Next you will need to remove the comment form filter hook used by the captcha plug-in and instead set up your meta field filter to call your function.
You can review an example of how to do this with the ‘math captcha’ plug-in by BestWebSoft in the examples folder.
